In one form or another, physics is one of the oldest academic disciplines, and possibly the oldest through its modern subfield of astronomy. [4] Sometimes synonymous with philosophy, chemistry and even certain branches of mathematics and biology during the last two millennia, physics emerged as a modern science in the 16th century [5] and is now generally distinct from these other disciplines; although the boundaries between physics and all these other subjects still remain difficult to define.

Generally seen as an important subject, advances in physics often translate to the technological sector, and sometimes resonate with the other sciences, and even mathematics and philosophy. For example, advances in the understanding of electromagnetism lead to the widespread use of electrically driven devices (televisions, computers, home appliances etc.); advances in thermodynamics led to the development of motorized transport; and advances in mechanics led to the development of the calculus, quantum chemistry, and the use of instruments like the electron microscope in microbiology.

Today, physics is a broad and highly developed subject that is, for practical reasons, split into several general subfields. In addition to this, it can also be divided into two conceptually different branches: theoretical and experimental physics; the former dealing with the development of new theories, and the latter dealing with the experimental testing of these new, or existing, theories. Despite many important discoveries during the last four centuries, many significant questions about nature still remain unanswered, and many areas of the subject are still highly active.

A Vast and most Excellent Science
How often at night
When the heavens were bright
with the light of the glittering Star and Moon
have I stood there amazed and asked as I gazed
if their glory exceeds that of ours.
-Anonymous&H2O-

Anyone who has never made a mistake has never tried anything new.-Albert Einstein-

The Atom and the Quantum
Hail to Max Planck, Einstein, Bohr, Pauli, Broglie, Schrödinger, Feynman,
and Young man in the Future from the worshipful! You are the Master by
whom we are led. Awed by your cryptic and proud affirmations. Each of us,
driven half out of their head, still remains true to you
wouldn't say boo to you, Swallows your theories from Alpha to Zed,
Even if (drink to him, tankards must clink to him!) None of us fathoms
a word you have said
-George G.& H2O-

Particles and Waves
We are trapped by language to such
a degree that every attempt to formulate
insight is a play on words.
(2πrmv = n h)
n = 2πr/λ
n = an integral number
λ = wave length
h = Planck's Constant
2πr = Circle's Constant (Orbit equation)
-Niels Bohr& -H2O-

Does God Play Dice?

But you tell me of an invisible planetary system
where electrons gravitate around a nucleus. You explain
this to me with an image, I realize then that you have been
reduced to poetry:
" I shall never know. I have the time to become indignant?
you have changed theories. so that the sciences that was
to teach me everything ends up in a hypothesis,
that lucidity founders in metaphor, that uncertainty
is resolved in a work of art

-A.Camus, The Myth of Sisyphus.-

Schrödinger's Cat
The law of chaos is the law
of ideas, of improvisations
and seasons of belief

The Dreams stuff is made of

Like a gleam in the darkness, we have appeared
for an instant from the black nothingness of the
ever-unconscious matter, in order to make good
the demands of reason and create a life worthy
of ourselves and of the Goal we only dimly perceive
-Andrei Sakharov-

Quantum field Theories
"The nature of a field is completely determined by
the properties of the particle that transmit it,
while the nature of a particle depends solely on
the ways in, which it couples to fields.
QED = Quantum Electrodynamic
α = e2/ħc
QCD = Quantum Color Dynamic (Quantum Foam)
rp = Second root of Għ/c3 = 1,6 x 10-35(power) it is Planck's Length
-Richard Feynman,Julian Schwinger, Murray Gell-mann and George zweig

The whole Shebang
I am astounded by people who want
to "know" the universe when it's hard
enough to find your way around the world
-H2O-
